Abstract: ABSTRACT OF THE DISCLOSURE      A system and process are provided for recovering copper from a contaminated copper-bearing source such as copper smelter flue dust.  In carrying out the process the copper-bearing source is leached in an acidic solution to produce a liquor containing dissolved copper and dissolved contaminants.  Simple copper sulfides are precipitated from the liquor by reacting the liquor with chalcopyrite and sulfur dioxide.  Copper is recovered from the precipitated sulfides.  The system for recovering copper from a copper-bearing source includes a multi-stage countercurrent leach circuit which utilizes an acidic leach solution to produce a liquor containing dissolved copper.  The circuit has a first stage to which the copper-bearing source is introduced and a final stage wherein the leach solution contains greater than about 150 gpl sulfuric acid.  In addition there is provided a precipitation circuit wherein the liquor is reacted with chalcopyrite solids and sulfur dioxide to precipitate dissolved copper from the liquor as simple copper sulfides.  Finally, there is provided a copper recovery circuit for recovering copper from the simple copper sulfides.      A novel process is provided for precipitating simple copper sulfides from a solution containing both dissolved copper and dissolved contaminants.  The solution is combined with precipitation product such that substantially all ferric iron contained in the solution is reduced to ferrous iron.  The ferric-free solution is reacted with chalcopyrite solids and sulfur dioxide to precipitate the dissolved copper as simple copper sulfides.

Abstract: Abstract of the Disclosure An end reversing roller for a conveyor band of wire mesh is arranged at the delivery end of a freezing canal. The end reversing roller is provided with axially extending slats. The outer surfaces of the slats are spaced from the  shaft of the reversing roller, a distance which is greater than radius of the cylindrical surface which the wire mesh otherwise would follow. Accordingly, the outer surfaces of the slats will engage the inner surface of the wire mesh whereby the wire mesh is caused to expand. Accordingly, a rela-tive movement is achieved between the wire mesh and the  material or the product which have been frozen in  the freezing  apparatus. Ac-cordingly, an effective breaking-off of the frozen material or the frozen product with respect to the wire mesh is achieved.            (Fig. 1A)

Abstract: ABSTRACT OF THE DISCLOSURE         Sulphuric acid leaching has been used in the treatment of lateritic ores for the recovery of nickel and cobalt there-from.  However, in order to obtain good extraction from these ores, prolonged treatment using acid of high strength and also using high pressures and recylcing steps have been necessary.  In the improves method of the invention nickel and cobalt is solubilized from high-magnesia nickeliferous serpentine ores by leaching the ore with an aqueous solution of sulphuric acid while adding to the solution a reducing agent to maintain the redox potential of the solution at a value between 200 and 400 milivolts, measured against the saturated calomel electrode.  This improved procedure increases the reactivity of the serpentine and results in maximum extraction of nickel consistent with minimum extrac-tion of iron and magnesia and minimum acid consumption.

Abstract: ABSTRACT OF THE DISCLOSURE         An adsorption process for the recovery of hydrogen from a hydrogen-containing gaseous mixture wherein particulate adsorbent solids with a magnetiza-ble component, or components, are contacted at low tem-perature with the gaseous mixture in an adsorption zone and hydrogen is concentrated in the off gas by the selective adsorption of the non-hydrogen components on the solids which are then circulated to a hydrogen dis-placement zone to free any occluded hydrogen and then to a desorption zone in which the exhausted solids are regenerated by the use of higher temperatures.  The solids are formed into a magnetically stabilized moving, fluidized bed.  The residual hydrocarbons in the desorbed solids are subsequently displaced, suitably with hydrogen, steam or water by contact in a magnetically stabilized bed of the solids.  When steam is used, the wet solids are then dried by contact with hydrogen to displace the water, and cooled to complete the regeneration.

Abstract: ABSTRACT           A roll of convoluted crepe paper, thin plastic foil or like web material has an outer side which is provided with a continuous coat of adhesive, transversely extending uniformly spaced weakened portions in the form of perforations or slits, and layers of a material which does not adhere to the adhesive.  Such layers are applied to the inner side of the web so that they flank the weakened portions and allow for rapid engagement of the leader of the web by two fingers when the user wishes to remove one or more sections or panels between neighboring weakened portions.  The roll can be used for the cleaning of garments or for analogous purposes and can be made in an apparatus wherein the application of layers of non-adherent material precedes or follows the making of weakened portions.  The length of each layer, as considered in the longitudinal direction of the web, is a small fraction, preferably less than one-third, of the distance between two neighboring weakened portions.
